Project duration: 2012 - 2017

Funding organisation

Primary research aim

To implement and assess the impact of an intervention using a salt substitute on blood pressure at the population level using a stepped wedge trial design.

Research objectives and methodology

Phase 1: To assess predisposition patterns towards incorporating the new salt substitute into daily cooking among villagers, authorities and other potential stakeholders, in order to inform and construct the structure of the intervention in the local communities and ensure successful implementation. For this, we will use focus groups and in-depth interviews techniques.

Phase 2: To implement and assess the impact of an intervention using a salt substitute on blood pressure at the population level using a stepped wedge trial design.

Current status

Phase 1 has concluded. Phase 2 enrollment has concluded. Implementation of the intervention in progress.
